For 28 years, Sitong Packaging Group has been a trusted PP woven bag manufacturer and polypropylene woven bags manufacturer, delivering reliable polypropylene woven bags (PP woven sacks) to agriculture, food, construction, fertilizer, chemical and mining customers across global markets. We manage every stage of production in-house — from raw material selection and tape extrusion to circular weaving, lamination, printing, cutting, sewing and quality inspection — and supply both wholesale and private-label buyers.
Every step is controlled in our own factory, so strength, print quality and lead time stay under our roof.
A single plant where every production step is meticulously managed for consistent quality and high efficiency — see the scale for yourself.
We primarily use 100% virgin PP resin for food-grade and high-strength bags, with recycled-content options available for cost-sensitive industrial packaging. Every batch is inspected, accurately blended and tested before production for consistent strength and performance.
As a PP woven bag manufacturer, supplier and factory, we inspect from raw materials to finished bags — size, weight, strength, printing and stitching — before shipment.
